In this direction, the boarding of Mauss becomes important (1974), when dealing with the term reciprocity, where it affirms that it is an act to give of generous and gratuitous form, to receive and to repay, forming a process of solidarity, mutual aid, fortifying the confidence, therefore in the act to give it exists more than a mere exchange, therefore it all exists a present symbolism that strengthens human values beyond the involved economic values. For Tesch (1999), social relations of reciprocity influence of determinative form in the formal structures (associations, cooperatives) that they possess norms and rules, that is, you are welcome are valid the rules if in the personal relations conflicts exist that generate the disaggregation of the group or association. The author cites despite diverse groups if extinguish with good economic incomes for the lack of reciprocity in the relations between its members. A priori, the nets if establish in the direction to promote the development local, but for such a minimum degree of social organization is necessary, thus allowing, to the involved actors, participation in the process (GRAZIANO Da Silva, 2001). In this direction, Mior (2005) complements that from a process of problematic internalizao of the regional one, pro-active positions in the construction and implementation of new strategies of development are assumed, strategies these, found through the verticalizao (vertical nets), which the author characterizes as being the form as agriculture it is incorporated in ampler processes of production, food transformation, distribution and consumption and substances cousins, inside of a sectorial boarding of the development. The nets do not serve as a model of agricultural development, but if it must recognize that they exist ' ' different types of nets interacting in distinct ways with the set of preexisting conditions, this implies that strategies adopted for the development agencies need if to adjust to the different areas rurais.' ' Then the term net goes to vary as the context that will be used (MURDOCH 2000, apud MIOR, 2005:21). Other leaders such as Sergey Brin offer similar insights.
